Systems and Methods for Optimizing Memory Allocation for Neural Processing Unit with Notebook in Closed Position

The present disclosure relates in general to information handling systems, and more particularly to systems and methods for optimizing memory allocation for a neural processing unit in a notebook while the notebook is in a closed position.

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

One type of information handling system is a notebook computer, which may also be referred to as a laptop. A notebook may comprise a display assembly rotatably coupled to a keyboard assembly via a hinge, allowing a user to open the display assembly relative to the keyboard assembly to a desired angle, as well as close the keyboard assembly relative to the display assembly to an angle of approximately zero degrees.

Increasingly, notebooks are being designed to remain at least partially functional and undertake particular tasks when closed. For example, a notebook may playback audio, conduct an audio conference, record audio, or undertake other tasks while closed. As another example, a notebook may perform advanced artificial intelligence functions when a notebook is in a closed position using a neural processing unit. Accordingly, it may be desirable to optimize memory capacity for use by a neural processing unit when a notebook is in a closed position.

In accordance with the teachings of the present disclosure, the disadvantages and problems associated with traditional approaches to functionality of a notebook in a closed position may be substantially reduced or eliminated.

In accordance with embodiments of the present disclosure, an information handling system may include a keyboard assembly, a display assembly rotatably coupled to the keyboard assembly, a memory housed within one of the keyboard assembly and the display assembly, a storage resource housed within one of the keyboard assembly and the display assembly, and a processor housed within one of the keyboard assembly and the display assembly and communicatively coupled to the memory and the storage resource. The processor may be configured to, in response to the display assembly being manipulated from an open position to a closed position relative to the keyboard assembly, determine services of the information handling system needed in a special mode of operation of the information handling system that executes in the closed position, determine services of the information handling system needed in a normal mode of operation of the information handling system that executes in the open position which are not needed in the special mode of operation, and cause memory allocation within the memory of services needed in a normal mode of operation which are not needed in the special mode of operation to be transferred from the memory to virtual memory within the storage resource.

In accordance with these and other embodiments of the present disclosure, a method may be provided for an information handling system comprising a keyboard assembly, a display assembly rotatably coupled to the keyboard assembly, a memory housed within one of the keyboard assembly and the display assembly, and a storage resource housed within one of the keyboard assembly and the display assembly. The method may include, in response to the display assembly being manipulated from an open position to a closed position relative to the keyboard assembly, determining services of the information handling system needed in a special mode of operation of the information handling system that executes in the closed position, determining services of the information handling system needed in a normal mode of operation of the information handling system that executes in the open position which are not needed in the special mode of operation, and causing memory allocation within the memory of services needed in a normal mode of operation which are not needed in the special mode of operation to be transferred from the memory to virtual memory within the storage resource.

In accordance with these and other embodiments of the present disclosure, an article of manufacture may include a non-transitory computer-readable medium and computer-executable instructions carried on the computer-readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to, in an information handling system comprising a keyboard assembly, a display assembly rotatably coupled to the keyboard assembly, a memory housed within one of the keyboard assembly and the display assembly, and a storage resource housed within one of the keyboard assembly and the display assembly, in response to the display assembly being manipulated from an open position to a closed position relative to the keyboard assembly: (a) determine services of the information handling system needed in a special mode of operation of the information handling system that executes in the closed position; (b) determine services of the information handling system needed in a normal mode of operation of the information handling system that executes in the open position which are not needed in the special mode of operation; and (c) cause memory allocation within the memory of services needed in a normal mode of operation which are not needed in the special mode of operation to be transferred from the memory to virtual memory within the storage resource.

Generally speaking, virtual memory is a memory management technique that provides an abstraction of the storage resources that are actually available on an information handling system which creates an illusion to users of a very large memory. In other words, operating system, using a combination of hardware and software, may map memory addresses used by a program, called virtual addresses, into physical addresses in memory. Storage resource, as seen by a process or task executing on processoror neural processing unit, may appear as a contiguous address space or collection of contiguous segments. Operating systemmay manage virtual address spaces and the assignment of real memory to virtual memory. Address translation hardware in the processor, often referred to as a memory management unit (MMU), may automatically translate virtual addresses to physical addresses. Software within operating systemmay extend these capabilities, utilizing, e.g., storage resource, to provide a virtual address space (i.e., virtual memory) that may exceed the capacity of real memory and thus reference more memorythan is physically present in information handling system.
